It is provided a method for determining when access control of an electronic lock, controlling access to a restricted physical space, should be performed. The method is performed in an intent determiner and comprising the steps of: obtaining movement data from a first sensor of a portable key device, the movement data indicating movement of the portable key device; obtaining a distance indicator from a second sensor, the distance indicator being indicative of distance between the electronic lock and the user; determining when there is user intent to open based on both the movement data and the distance indicator; and triggering access control to be performed only when user intent has been determined.

An intelligent electronic lock for receiving an identification signal and an induction signal includes a housing, a wireless sensor, a current divider, a microcontroller, a driver and at least one blocking element. The wireless sensor, the current divider, the microcontroller and at least one blocking element are disposed in the housing. An induction coil of the wireless sensor senses the induction signal to generate an induction current. The wireless sensor receives the identification signal. The current divider distributes the induction current to the microcontroller and the driver. The microcontroller obtains a target identification information from the identification signal. The microcontroller compares the target identification information with a reference identification information to output a control signal. The driver drives at least one blocking element to move between an unlocking position and a locking position. Based on the aforementioned description, the intelligent electronic lock is able to operate without power.

An example security system includes a plurality of access control devices that each control access to a respective secured area. A mobile device includes a processor, an accelerometer, a wireless transceiver, and memory storing a credential. The processor is configured to receive an indication from the accelerometer, detect a user gesture based on the indication from the accelerometer indicating a predefined movement of the mobile device, determine a pathway based on the gesture that includes multiple ones of the secured areas, and utilize the wireless transceiver to automatically transmit the credential to the respective access control devices associated with each secured area of the pathway. An example method for a security system is also disclosed.

In general, aspects of this disclosure are directed towards techniques for using a computing device to perform the functionality of a vehicle key, so that the computing device may be used to automatically unlock the doors of a vehicle and/or to activate a previously-deactivated keyless ignition system. The computing device may be associated with a vehicle, including sending an identifier associated with the computing device to the vehicle via short-range communication. The computing device may also send to the vehicle, via short-range communication, at least one unlock door signal including an access code verifiable by the vehicle, and wherein receipt of the at least one unlock door signal by the vehicle enables the vehicle to unlock one or more of its doors without further user intervention.

Disclosed is an access device of a vehicle having an on-vehicle control device configured to transmit enquiry signals to a mobile identification transmitter to determine the state of motion thereof, and adapt the transmission of the enquiry signals for a response signal received from the mobile identification transmitter containing the state of motion of the mobile identification transmitter, or on the basis of the absence of the response signal. Energy is saved in the event of a response signal containing a communicated stationary state of the mobile identification transmitter or in the absence of a response signal by reducing the frequency of the transmission of the enquiry signals.
